Idea? - use an old smartphone Vodafone 858 that is smaller than number one tester - a current Vodafone VFD-300.
Out with the weighing machine.
The old 858 is 99g complete and 69g minus battery and back cover
The new VFD-300 is 103g complete and 65g minus battery and back cover.
I had not thought of flying without the back cover until now but I get that idea from doing this exercise. Minus back cover does look possible, maybe with cling wrap as a dust cover, and it saves 10g for the VFD-300. The construction weight budget goes up to 146g.
